Abstract

The invention discloses an open-pit mine emulsion substrate suitable for remote distribution and an emulsion explosive prepared from the open-pit mine emulsion substrate. The open-pit mine emulsion substrate suitable for remote distribution is prepared by mixing a W component and an O component according to a weight ratio of (93-95):(5-7); the W component comprises the following raw materials in parts by weight: 77-85 parts of ammonium nitrate, 14-25 parts of water and 0.05-0.3 part of an additive, wherein the additive is sodium thiocyanate; and the O component comprises the following raw materials in parts by weight: 70-85 parts of diesel oil or mineral oil and 15-30 parts of an emulsifier. The emulsion substrate provided by the invention can be pumped for multiple times and transported for a long distance without crystallization and demulsification, and the mode of centralized production and remote distribution of the emulsion substrate is adopted, so that production sites of the emulsion explosive substrate can be reduced, the production costs of the explosive are reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of civil explosive production. More specifically, the present invention relates to an open-pit mine latex matrix suitable for remote distribution and an emulsion explosive made from it. Background technique [0002] Latex matrix is ​​the semi-finished product of on-site mixed emulsified explosives. Through the action of emulsifier, the droplets of oxidant aqueous solution mainly composed of ammonium nitrate and sodium nitrate are evenly distributed in the continuous medium of oil phase; The sensitizers are mixed and then pumped into the blast hole, sensitized and foamed for 20 to 30 minutes to form an explosive with detonator sensitivity or no detonator sensitivity. [0003] The general latex matrix has poor anti-turbulence and short storage life. Usually, a mine needs to be equipped with a ground station mode, which has problems such as high investment costs; the application of latex matrix suitable for re...
